WATER-HEATING FIREPLACE; GRATE.

Applicationdfiled August 537, 1924. Serial No 734;,5l185 To aZZ "whom z't mag ooac'ermf Belt known that l, MARTLN Donornxa citi zen oil the Ui'iited States, residing at V -ash aims to provide a novel and -.i11'iproved basket grate through which water can flow which the grateis connected.

.Anothcr object 1s the provision of a water to be heated so to.,lieat a radiator to i 3 receptacle on the radiator. and connected to the hot water flow pipe'l ietween the grate and radiator tokeep theradiator and channel ,oit the grate fullo'f Water, and for the further purpose of hun'iidiiying the air. in the room and afiording asupply of hot waten.

Vith the foregoing and other objects in view, which will be apparent asthe descrip tion proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it-being understood that changescanbe made within the sc'opeof what is claimed, without de partingfrom the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a front View showing the improved grate in a fireplace and connected with the radiator.

Fig. 2 is a perspective view of the improved grate.

Fig. 3 is a perspective View of the stand which supports the bottom of the grate.

Fig. 4 is a plan View of the bottom and stand of the grate, with the walls of the grate omitted.

The grate, including its stand, is composed of piping, and may be 01' different sizes. The grate is of rectangular form as shown.

.The stand (shown by itself in Fig. 3) comprises the pipe sections 10, 11, 12 and 13 which are connected, excepting between the pipe sections 10 and 13 by elbows 14 and 14, thus connecting said pipe sections in series. The elbows have three branches including depending branches into which supporting legs 15 are secured. Said legs may be of pipe sections, with capslh secured on the. lower ends thereofto'close said legs and rel-mast to set on the bottom of the fire-. place orj hearth, The elbow 14;, is offset between. the; pipe sections 12 and. 13110 bring the pipe section 13: substantially.horizontal' slightly above horizontal plane of the pipe sections 10, 11 and 12. The forward end. of the pip'e section 10 is connected byan.

elbowl'i'jwith the upperjend of a vertical pipe section 18 whicl'iiorms'"thetourthleg of the stand, and said pipe section extend down'through the floor, as seen in:

Fig. 1. The pipe section 18 provides cold water inlet for the grate.

The bottom of the grate comprises a zig the" zag coilj corhposed of the parallel pipeseo tions l 9 'which, as shown, are arranged parallel with :one another and. with .the front and rear-p pesections13 and 11, respectively, ofthe standj, Elbows 2O 'are'used' for connecting the ends or the pipe section,

19 so that said pipe sections are connected in series, and the correspondlng end of the foremost pipe section 19 is similarly connected by' elbows 2.0 with the pipesection 13. The elbows, 20 are used in preference toU-couplings, in. order to space thepipe seetions-19 apart suificiently sothat the ashes can. pass down throughthe bottom for. the grate without cloggingflthe'slotsbetween the pipe sections 19. The elbows 20 rest on the pipe sections 10 and 12 of the stand, so that the bottom'of the grate is supported in a substantial manner by the stand.

The walls of the grate constitute a rectangular coil, and each wall is composed of vertically spaced pipe sections 21. Said pipe sections ofthe adjacent walls are connected by elbows 22, to connect the pipe sections 21 in series, and the lower pipe section 21 of the rear wall is connected by elbows 24t with the rearmost pip section 19 of the bottom, so that the water flows from the bottom into the pipes of the walls of the grate. The elbows 22 are formed with enlargements or balls 23 that are seated on one another in superposed arrangement, in order to space the pipe sections 21 apart a desired amount. This provides slots between the pipe sections 21 of sufiicient width to enable a poker to be inserted through said slots tor agitating the coal or wood in the grate and also to facilitate the discharge of ashes and clinkers from the grate. The lower pipe sections 21 and elbows 22 are supported on the bottom of the grate.

A hot water flow pipe 25 is connected by an elbow 26 with the last pipe section 21 of the series, preferably above one rear corner of the grate, and leads upwardly to the upper portion of a suitable radiator 27. A cold water return pipe 28 leads from the lower port-ion of the radiator to the hollow leg or pipe section 18 of the stand.

The pipe sections 10, 11, 12 and 13, which V This provides for the thermal-siphonic flow of water through the grate and radiator, inasmuch as the water when heated in passing through the conduit or channel of the grate will flow upwardly to the radiator, while the water in coo-ling in the radiator will flow downwardly through the pipe 28 back to the grate. This provides for an automatic circuitous flow of water through the grate and radiator. p

The grate may be used for solid fuel, such as wood and coal, and may also be used for liquid and gaseous fuel by providing a suitable burner therein or thereunder, and the grate might also be used in connection with an electrical heater.

A tank or receptacle 29 is seated on the radiator and has a lower drain pipe 30 connected to the pipe 25, such as by means of a T-coupling 31. Water can be poured into the tank 29 from time to time, to keep'the tank filled, and this will keep the radiator27 filled with water. Furthermore, the tank being seated on the radiator will be heated so as to heat the water therein. This is of advantage in order to humidify the air in the room, as well as to afford a supply of hot .water. The water can be taken from the tank 29 when hot water is wanted.

Having thus described the invention, what is claimed as new is 1. A water-heating basket grate comprising a stand having a cold water inlet and a water passage leading from said inlet, a bottom coil resting on the stand and connected with the stand for the upward flow of the water from said passage through the bottom coil, and a side wall coil resting on the bottom coil and having an upper hot water outlet, said side wall coil having a lower con nection with the bottom coil for the up ward flow of water from the bottom coil through the side wall coil.

2. A water-heating basket grate comprising a stand having a frame and supporting legs, said frame having a water passage with a cold water inlet, a zig-Zag bottom coil resting on said frame and connected at one end with said frame for the upward flow of water from said passage through the bottom coil, and a side wall coil resting on the bottom coil and having a hot water outlet at its upper end, the lower end of the side wall coil being connected to the other end of the bottom c-oil for the upward flow of water from the bottom coil through the side wall coil, the bottom coil being composed of pipe sections and elbows connecting them and seated on the frame, and the side wall coil being composed of vertically spaced pipe sections connected by elbows seated one on the other.
